The Grade 1 Maths outcomes from the Australian Curriculum are sorted into learning areas and graphically displayed to show a logical teaching sequence. The aim would be to use this arrangement to plan for units so no learning outcomes are missed.
This is an adapted version of my earlier Maths Scope and Sequence - Australian Curriculum for Grade 2 but, because there are 4 categories not explicitly covered in grade 1 (Multiplication and Division, Area, Mass and Transformation) there is more Addition and Subtraction. You would need to determine other categories you would like to reinforce in place of Area, Mass and Transformation.
This Scope and Sequence has outcomes arranged both by the Australian Curriculum Content Strands and also re-arranged to show my timeline to ensure that all outcomes are met over an academic year.
The sequence also takes into account where content requires prior learning (such as halves for teaching time with clocks).
I hope this will make planning your teaching sequence much easier.
